Complete penetration section fireproof panel structure of duct and the like between beam low wall

摘要

(57) Abstract Objective The metal make framework panel operation as a wall receivingSo, even with application of the kind of fire-protection wall which causes the opening with under the beamIt to be possible to designate the opening as fire proof construction simply, in addition, the goldThe duct or pipe arrangement the Interpolation is done in the perforation hole of the being attached make framework panel, it is denseWith distribution facilities are produced these ducts or pipe arrangement simply. Constitution Between under beam 2 and top of fire-protection wall 3, top beam 2The metal which it joins to the bottom surface, supports the fire-protection wall 3 top in the bottomMake to provide framework panel 7 as the foundation of the refractory material this metal make frameworkDuct 5 or pipe arrangement in the perforation hole 9 of panel 7 the Interpolation.
